Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an acetic acid odor reducing agent and an acetic acid odor reducing method. More specifically, acetic acid and / or
Also, the present invention relates to an acetic acid odor reducing agent and a method for reducing acetic acid odor comprising a specific surfactant used in a acetic acid-containing cleaning composition for a bathroom or kitchen around which vinegar is mixed.

[0002]

2. Description of the Related Art Stains in kitchen sinks consist of inorganic stains containing silicon or calcium as a main component and oily stains from cooking or tableware, and a tub in a bathroom, a floor or a wall of a bathroom,
The dirt adhering to the wash basin or the toilet in the toilet room is composed of oily substances, fatty acid metal salts, calcium phosphate and the like secreted from the human body. These stain components become stains that are very difficult to remove over a long period of time. Conventionally, as a detergent for removing these stains, an acidic detergent using hydroxycarboxylic acid or hydrochloric acid as an acidic substance, or a neutral or alkaline solution containing a sequestering agent represented by ethylenediaminetetraacetate and the like. Are known.

On the other hand, the cleaning effect of vinegar has been known for a long time, and JP-A-54-105108 discloses a method of cleaning with a detergent composition to which acetic acid and / or vinegar is added. However, when acetic acid or vinegar is added, a unique odor of acetic acid has to be put into use, so that a slight odor of vinegar must be tolerated during use, and there is a problem that the feeling of use of the product is significantly reduced.

[0004] In view of the above, a method of enhancing the feeling of use by adding a fragrance and masking the acetic acid odor is considered.
In order to mask the acetic acid odor, there is a problem that a specific fragrance having a high masking effect must be added in an amount corresponding to the masking effect of the fragrance.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide an acetic acid odor reducing agent comprising a component other than a fragrance component and a useful acetic acid odor reducing agent, in order to obtain an acetic acid-containing cleaning composition for use in bathrooms and kitchens which is excellent in use feeling. An object of the present invention is to provide a method for reducing acetic acid odor.

[0006]
